Many of Earth’s system’s interact at the ecosystem level
Ecosystem =
A change in just one biotic or abiotic factor can alter complex relationships and have large scale consequences
Ecosystems (and higher levels) are regulated by the flow of energy and the cycling of nutrients
Life is composed of energy and matter, which is always on the move
Projected decrease in transfer efficiency is expected to lead to a 21.3% decrease in abundance of predators in marine ecosystems
WATER
NITROGEN
Nitrogen is one of the fundamental building blocks for life on Earth, especially plants
Not all the nutrients in fertilizers get absorbed by plants and the excess moves its way into rivers, lakes, oceans and groundwater as agricultural runoff
CARBON
CARBON
Carbon is in carbon dioxide, which is a greenhouse gas that works to trap heat close to Earth
Carbon footprint is used as shorthand for the amount of carbon being emitted by an activity or organization
Biochemical cycles interact to regulate the biosphere, including climate →
Biochemical cycles interact to regulate the biosphere, including climate →
Biogeochemistry is a foundation of biomes: living things adapted to a specific regions →
Ecosystems are the interactions with the biotic and abiotic within those regions
Biogeochemical provinces are dynamic entities that change their spatial extent and position with climate and are expected to be perturbated in the near future by global change
